Volcanic activity worldwide 10 Dec 2013: Sinabung, Santa María / Santiaguito, Pacaya, Fuego, Klyuch...

Etna (Sicily, Italy): The New SE crater has remained calm; after the increase yesterday, tremor has descended back to low levels and continues to fluctuate.

Klyuchevskoy (Kamchatka): Relatively strong ash emissions continue. This morning, the plume rose to about 27,000 ft (7 km) altitude, drifting NW.

Bagana (Bougainville Island, Papua New Guinea): New explosions occurred this morning. An ash plume rose to 10,000 ft (3 km) altitude this morning and drifted 20 nautical miles to the east (VAAC Darwin).

Sinabung (Sumatra, Indonesia): After a relatively calm period, a large vulcanian explosion occurred at the volcano this morning (04:30 GMT). VAAC Darwin reports an ash plume to 38,000 ft (12 km) altitude drifting 50 nautical miles to the NW.
The eruption was preceded by a smaller one at midnight (GMT) with an ash plume altitude of estimated 18,000 ft (5.5 km).
The volcano has been on red alert for 2 weeks and more than 17,000 people remain evacuated (for good reason!).

Santa María / Santiaguito (Guatemala): The observatory reports little changes: an explosion occurred with an ash plume of 900 m height, and avalanches continue to descend from the active block lava flows.

Pacaya (Guatemala): Judging from INSIVUMEH's brief daily report, strombolian activity has decreased as ejecta heights were described as 25 meters (vs 50 m previously).

Fuego (Guatemala): INSIVUMEH reports 7 explosions during the past day with ash plumes up to 700 m height.
